Titans C Eugene Amano has been diagnosed with a torn triceps, and is done for the season.
Amano has been the Titans' starting center since 2008, but the team opened his job to competition following a dismal 2011, where he graded out as Pro Football Focus' fourth worst center. Fernando Velasco, Kevin Matthews and UDFA William Vlachos will now compete for the job, with Velasco as the favorite. The Titans may still explore a dried-up free agent market. Due a salary of $3.685 million in 2013, Amano has likely played his last snap with Tennessee.

Titans coach Mike Munchak was impressed with Chris Johnson's performance in Monday's controlled scrimmage with the Falcons.
"...Chris had some great reads. The way he was hitting things, you don’t see hesitation," Munchak said. "I think C.J. looked quick, he was hitting things decisively. When he decided to go outside he hit it hard and showed some speed around the edge." CJwhateverK has been creating a lot of "he's back" buzz since the beginning of Titans camp, but we aren't likely to get an extended look at his reclamation tour in Saturday's preseason opener. Tennessee's second exhibition game is a week from Friday.
